The short version
BNY Mellon Ultra Short Income ETF (BKUI) is an actively managed bond fund. It holds short-term, investment-grade debt and cash equivalents, and at least 25% of its assets are in bank obligations. Its 0.12% expense ratio is below the 0.18% average of similar ultra-short funds, though iShares' ICSH and Vanguard's VUSB cost less. It aims for monthly income with very small price swings, but it is not a money market fund.

How it works
BKUI does not track an index. Its sub-adviser, Dreyfus, a division of Mellon Investments Corporation, picks the holdings. The fund normally puts at least 80% of its net assets in investment-grade, US-dollar debt or cash equivalents. These can be fixed, variable or floating rate. They include corporate bonds, asset-backed securities, repurchase agreements (short-term loans backed by collateral), commercial paper, certificates of deposit, US Treasuries, and debt from foreign governments and companies. At least 25% goes to bank obligations, so the fund is concentrated in the banking industry.
The manager normally keeps effective duration, a measure of how much prices react to interest rates, at one year or less. It may run longer when rates are volatile. The portfolio's average credit rating must be at least A, and each purchase must be rated at least BBB- or sit in the top two short-term tiers. The manager pairs a top-down economic view with bond-by-bond valuation work, and shifts duration based on where it expects rates to go. Portfolio turnover was 13.55%.
As of June 30, 2026, the fund held 157 positions, and the top 10 made up 12.64% of assets. The largest were a Norddeutsche Landesbank note (2.5%), Old Line Funding commercial paper (2.1%) and a Treasury note due January 2028 (1.7%). About 48% was classified as cash and cash-like holdings. Bonds and notes made up 50.7%, with an average maturity of 1.6 years. The share price is not fixed at $1.
What it really costs
- BKUI charges 0.12% a year, versus an average of 0.18% for the similar funds below (3rd of 8, cheapest first).
- Using the prospectus's standard example, $10,000 invested would cost about $12 in the first year and $154 over 10 years (assuming a 5% annual return).
| Cost of $10,000 (SEC example) | 1 yr | 3 yrs | 5 yrs | 10 yrs |
|---|---|---|---|---|
| BKUI | $12 | $39 | $68 | $154 |
Structure and tax notes
- Bond prices move opposite to interest rates; the longer the maturities it holds, the more its price reacts to rate changes.
In a retirement portfolio
It holds short-term, high-quality debt and has rarely lost more than a percent or two, so it can work as a low-volatility reserve.
BKUI launched in August 2021, so it has no record from the 2008 financial crisis or the 2020 COVID crash. In the 2022 bear market, it fell 1.4% between January 3 and June 14, 2022, and got back to its old high in about seven months. Its deepest drop ever was 1.7%. Its worst calendar year was 2022, with a loss of 0.11%. For someone who may need to sell shares in a bad year, those small losses are the main appeal. The trailing 12-month yield was 4.01% as of October 27, 2026, paid monthly. Costs are low: $12 in the first year on $10,000 in the SEC's standard example. Drawbacks: income falls when short-term rates fall, the fund isn't FDIC-insured, its bank concentration adds credit risk, and long-term growth is modest. Past results don't predict the future, and a plan should look at the whole portfolio, not one fund.
Who it may suit — and who should look elsewhere
May suit
- Retirees setting aside one to two years of spending money who accept small price moves in exchange for monthly income.
- Cost-aware investors wanting an actively managed ultra-short fund at 0.12%, below the 0.18% average of its peers.
- Investors comfortable with bank exposure: at least 25% of the fund goes to bank obligations, alongside commercial paper and short corporate notes.
Look elsewhere if
- Anyone who needs FDIC insurance or a stable $1 share price. BKUI is neither a bank deposit nor a money market fund.
- Investors focused on the lowest fee. ICSH charges 0.08% and VUSB 0.10%, compared with BKUI's 0.12%.
- Investors seeking long-term growth. Since inception, it returned 3.57% a year through December 31, 2025.

Questions investors ask
Is BKUI a money market fund?
No. The prospectus says BKUI is not a money market fund and does not try to keep a stable $1.00 share price, so its price moves up and down. It is also not a bank deposit and is not insured by the FDIC. It does hold many money-market-type instruments, such as commercial paper and certificates of deposit, along with short-term corporate bonds and Treasuries.
Does BKUI pay monthly dividends?
Yes. BKUI pays income every month. As of October 27, 2026, its trailing 12-month yield was 4.01%, or about $1.99 per share. Because the fund holds short-term and floating-rate debt, its payouts tend to follow short-term interest rates. If rates fall, the monthly income will likely shrink, since maturing holdings are reinvested at lower yields.
What's the difference between BKUI and ICSH?
ICSH is the closest match by maturity and issuer mix, and it costs less: 0.08% a year versus BKUI's 0.12%. Both are actively managed ultra-short bond ETFs. As of October 27, 2026, their price returns were the same: 3.5% over one year and 4.9% a year over three years. ICSH had about $8.1 billion in net assets as of July 31, 2026, compared with BKUI's $575 million as of June 30, 2026. BKUI must also keep at least 25% in bank obligations.
Can you lose money in BKUI?
Yes, but so far the losses have been small. Its worst quarter was a 0.97% drop in the first three months of 2022, and it lost 0.11% for all of 2022. Its biggest decline from peak to low was 1.7%, between August 2021 and June 2022, and it took about seven months to recover. A sharp rise in rates, a credit problem at a bank or other issuer, or trouble in the banking sector could cause larger losses.
What does BKUI invest in?
BKUI holds short-term, investment-grade debt and cash equivalents. As of June 30, 2026, it had 157 positions. The largest were a Norddeutsche Landesbank note (2.5%), Old Line Funding commercial paper (2.1%) and a US Treasury note due January 2028 (1.7%). It also held bonds from Royal Bank of Canada, Mizuho Bank, T-Mobile and Mastercard. About 48% was in cash and cash-like holdings, and the bonds had an average maturity of 1.6 years.
